A cueing paradigm was employed to examine modulation of distraction due to a visual singleton. Subjects were required to make a saccade to a shape-singleton target. A predictive location cue indicated the hemifield where a target would appear. Older adults made more anticipatory saccades than younger adults, and were less accurate for making an eye movement in the vicinity of a target. However, younger and older adults likewise benefited from the cue; distraction was reduced when the distractor singleton appeared in an uncued hemisphere. The ability to compensate for problems with distraction in older and younger adults through use of the precue suggests that attention to a general region of space, rather than a specific location, may be enough to modulate distraction.
采用一种提示范式来研究视觉单独元素引起的分心调制。要求受试者向形状单独的目标进行扫视。一个预测性位置提示表明目标将出现的半视野。老年人比年轻人做出更多的预期扫视，并且在目标附近进行眼球运动时准确性较低。然而，年轻人和老年人同样从提示中受益；当干扰单独元素出现在未提示的半球时，分心减少。通过使用预提示来补偿老年人和年轻人分心问题的能力表明，关注空间的一般区域而非特定位置可能足以调节分心。
